Hello! I am using InDesign CS4 and have created a docment with 2 spot colors but the preflight shows cmyk plus the 2 spots. Any ideas how I can find out why and get rid of the cmyk? Thanks!
Check your document using Separations Preview: View > Output > Separations Preview. From that palette, choose View: Separations, and then click to hide your spot inks. That should reveal any CMYK objects. Do you have any placed images?
If you go to your swatch palette and select "Add unnamed colors", you will see swatches from any cmyk colors used.
many forget that 0/0/0/100 and 0/0/0/0 will generate 4col plates.
also if any placed graphics contain CMYK info, it will be in the preflight.
Photos should be Mono/Dou/Tritones
Illustrator .ai or pdf formats will generate cmyk in Indesign Preflight.
Make sure they only have spot colours and try saving as .eps in Illy.
I find that will give you an accurate preflight.
This is related: We are using CS5.5 to design books, and it looks as though this problem is not solved. We do a LOT of 2/c books. Viewing separations is not that helpful, as we have to scroll through 128+ pages of a book to find often very thin/very small instances of black--which cannot be turned off in Preflight. Help! Is there any way to set up a document as 2/c ONLY?
